MIM-1AT3 Module 109
Step 2: Connect the SMB connector of another E3/T3 cable to the Rx port of
MIM-1AE3 module and another end to the Tx port on the device to be connected;
Step 3: Check the behavior of the LINK LED on the MIM-1AE3 panel. It is OFF
when fault has occurred on the link and signal is out of synchronization. In this
case, please check the link.
MIM-1AT3 Module
Introduction 1-port 44.736 Mbps ATM-T3 interface module (MIM-1AT3) supports:
■ Two ATM cell mapping modes: ADM and PLCP;
■ Scrambling in data transmission;
■ Both line clock (when working as DTE interface) and internal clock (when
working as DCE interface);
■ Four types of test measures, i.e., local cell loopback, local payload loopback,
remote payload loopback, and remote line loopback.

You are allowed to equip an H3C Series Router with MIM-AT3 modules to its full
capacity. Yet, you are recommended to install only one MIM-AT3 module on it,
whatever its model is, to ensure the performance of some key services.
Interface Attributes The interface attributes of MIM-1AT3 are given in the following table:
n
In the supported services described in the above table, CBR represents Constant
Bit Rate, rt_VBR represents Variable Bit Rate-Real Time, nrt_VBR represents
Variable Bit Rate-Non Real Time, and UBR represents Unspecified Bit Rate.
